Well as far I can read, nobody seems to understand the problem.
All I want is some sort of idea or information on how to make sure that equipment being designed for 220VAC is getting 220VAC even if the offered mains can climb up to 240VAC.
As it has to build in to these equipments all the proposed solutions are not applicable.
I appreciate all your time in writing to this forum but wished that the main question would be clear and some one could jump on the idea of a small unit that is to be build into the equipment, is cheap and solid state.
AT the moment the idea of using variac, transformer or SMPSU is the big idea by most of the writers.
It's to big, to expensive and to costly. Non of these comply to the question.
Thank you any way.
Cheers,
Tarzan
